Capacitor is series.

Let’s say we have two capacitors in series. . The capacitance can be found as .

 

Example :

· Find total Equivalent capacitance and the total charge delivered by the voltage source .

· Find Voltages across each capacitor

 

Finding Total Charge

Qt=Ct x V

Finding Voltage Across Capacitors

Capacitor in Parallel

Two capacitors are said to be in parallel if they share two common terminals

 

 

Example

For the following circuit

1. Find total Capacitance

2. Verify Charge across all Capacitors

 

Ct = 100pF+220pF+50pF
Ct = 370 pF

Verify Charge across all Capacitors
